Along with all the other Oracle quarterly patches comes VirtualBox 6.1.6.
I’ve done the installation on Windows 10, macOS Catalina, and Oracle Linux 7 hosts. All worked fine.
I’ve done some Vagrant builds with it and they worked too.
We are probably due a bunch of new Oracle updates (APEX, ORDS, SQLcl) and it wouldn’t surprise me if we get Oracle 20c on-prem in the next few days, so I’m sure I’ll be doing loads of fresh builds in the coming days. 🙂
